    • PROBLEM TO BE SOLVED: To provide a granular porous gunpowder having a high rate of gas evolution in combustion and a method for producing the same. SOLUTION: The method for producing the granular porous gunpowder includes a step of preparing a lacquer comprising a gunpowder component, an organic solvent and a nitrate and/or a sulfate, a step of preparing a granulation aqueous solution having specific gravity (20°C) of 1.0-1.1, and a heating step wherein the lacquer is added to the granulation aqueous solution and the granulation aqueous solution is heated under stirring to a temperature exceeding a boiling point of the organic solvent. The porous gunpowder has tentative specific gravity of 0.5-0.9 g/cm 3 . COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供具有高燃烧气体逸出速率的粒状多孔火药及其制造方法。 解决方案:制备粒状多孔火药的方法包括制备包含火药组分,有机溶剂和硝酸盐和/或硫酸盐的漆的步骤,制备比重的制粒水溶液的步骤(20 ℃)为1.0-1.1,加热步骤,其中将漆加入造粒水溶液中,将造粒水溶液在搅拌下加热至超过有机溶剂沸点的温度。 多孔火药的临时比重为0.5-0.9 g / cm 3。 版权所有(C)2009,JPO&INPIT
